Case Type   : 多节点写入
Case Name   : 备机在存储过程中进行只读查询
Create At   : 2023/07/04
Owner       : opentestcase033
Description :
    1.修改enable_remote_execute参数值为on
    2.主机创建表，创建存储过程
    3.备机在存储过程中进行只读查询
    4.备机查看日志打印
    5.环境清理，恢复参数
Expect      :
    1.修改成功
    2.创建成功
    3.执行成功
    4.不转发给主机
    5.环境清理成功，恢复参数成功
